Twitter is making sure that a soon-to-be nine-year-old boy has the best birthday ever despite the efforts of a persistent bully.

A Twitter user named Christopher (@Hopenlesmyth) asked people on Twitter if they knew of someone famous who could send birthday messages to his son Ollie for his ninth birthday. In a series of tweets, he explained that Ollie is being bullied by someone who keeps making him feel worthless, and that he could use some positive energy on his big day.

Radio DJs and broadcasters responded to his request.

Then celebrities like actor Russell Crowe and YouTube stars Alfie Deyes and Zoe Sugg sent their best.

Even ordinary people wanted to wish Ollie well.

Ollie's parents were overwhelmed by the number of kind, enthusiastic responses. As of June 30, Christopher's original tweet had over 6,500 replies and 14,000 retweets.

They might have broken Twitter, but are doing their best to try to respond to each one.

From all of us at INSIDER, happy birthday Ollie! Becoming an internet celebrity is definitely the best way to celebrate.
